COVID-19: Don’t use face shield in place of face mask, NCDC warns Nigerians

The Nigerian Centre for Disease Control (NCDC) has warmed against the replacement of the prescribed face mask with face shield with the aim of protecting oneself against contacting coronavirus.

The centre said face shield alone cannot give adequate protection as it is produced to be combined with face mask for maximum effect.

“SARS-CoV-2 which causes the coronavirus disease can spread from person-to-person through respiratory droplets, often through speaking, coughing or sneezing.

“There is evidence that the correct use of face masks reduces the risk of COVID- 19 infection.

“Given the limited evidence on the effectiveness of face shields in protecting people from COVID-19 infection in community settings, and the absence of recommendations on their use, by the WHO and other public health authorities, face shields alone should not be used in preventing the spread of the COVID-19 infection.

“When used, it should be done in combination with an appropriate face mask.

“Face shields are generally used in health care settings by medical professionals to provide barrier protection to the facial area, including eyes, nose and lips.

“Even in healthcare settings, face shields are not meant to function as primary respiratory protection to prevent infection.

“Face shields are used in combination with surgical mask or N95 mask by health workers for maximum protection during invasive procedures such as intubation.

“There are no published studies on the effectiveness of face shields against COVID-19 in non-healthcare settings,” NCDC said
